270 Chapter 4 Performing CCI Operations
4.13.5 Windows Subcommands
The CCI software provides subcommands for the Windows platforms which are executed as
options (-x <command> <arg>) of another command. When you specify a subcommand as the
only option of a command, you do not need to start HORCM. If another option of the
command and the subcommand are specified on the same command line, place the other
option after the subcommand.
4.13.6 Findcmddev Subcommand
The findcmddev subcommand (find command device) searches for command devices within
the specified range of disk drive numbers. If it is found, the command device is displayed in
the same format as in the configuration definition file. This subcommand is used when the
command device name is not known and when the HORCM is not started. Figure 4.51 shows
an example of the findcmd
dev subcommand used as an option of the raidscan command and
its output. Table 4.39 lists and describes the find
cmddev subcommand parameters.
D:\HORCM\etc> raidscan -x findcmddev hdisk0, 20
cmddev of Ser# 62496 = \\.\PhysicalDrive0
cmddev of Ser# 62496 = \\.\E:
cmddev of Ser# 62496 = \\.\Volume{b9b31c79-240a-11d5-a37f-00c00d003b1e}
This example searches for command devices in the range of disk drive numbers 0-20.
Figure 4.51 Findcmddev Subcommand Example
Caution: The findcmddev subcommand must be used when HORCM is not running.
Note: The findcmddev subcommand searches for the physical and logical drives associated
with the command device. If the command device is indicated as a logical drive in addition
to a physical drive, then a drive letter is assigned to the command device. You must delete
the drive letter assigned to the command device to prevent utilization by general users.
The “Volume{GUID}” must be made by setting a partition using the disk management
without file system format, and is used to keep as the same command device even though
the physical drive numbers are changed on every reboot in a SAN environment.
